Application led August 10, 1914. Serial No. 856,100.

To all lwhom it may concern:

Be it known that I, HERBERT A. Rnsrnfr- SKY, citizen of the UnitedStates, residing at Maplewood, in the county of St. Louis and State ofMissouri, have invented certain new and useful Improvements in RakeAttachments, of 'which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention has relation to improvements in wiper attachments forrakes; and it consists in the novel features of construction more fullyset forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of an ordinary hand-rakehaving my invention applied thereto; Fig. 2 is an enlarged top plan ofFig. 1, some of the parts being broken; Fig. 3 1s an end elevation ofFig. 2; Fig. 4 is a vertical cross-section on the zig-zag line 4-4 ofFig. 3, parts being left in elevation; Fig. 5 is a cross-sectionaldetail on the line 5 5 of Fig. 2; and Flg. 6 is a cross-sectional detailonl the line 6 6 of Fig. 2.

The object of my invention 1s to provide any of the varieties ofhand-rakes-w1th a wiper for the teeth thereof, sald wlper beingcontrolled by the operator from a polnt on the handle of the rake, andwithin 'easy reach of the hand of the person raking.

A further object is to provide a wiper which is simple in construction,one which is easilyl manipulated, and one possessing further and otheradvantages better'apparent from a detailed description of the invention,which is as follows:

Referring to the drawings, 1' represents the body of the rake, 2 theteeth thereof, 3 the shank and 4 the handle, as well understood in theart. Secured pivotally to a lug 5 on the body 1, (which lug is insubstantial alinement with the axis of the handle 4) is a bell-crank 6,the outer arm of which is pivotally coupled between terminal ears orlugs 8, 8, of a pair of straps 9, 9, the outer arms 9', 9, of which arebent or deflected toward the rake-body, and have their ends pivotallycoupled to ears'or lugs 10, 10, of a wiper plate 11 through openings oof which the teeth 2 are free to play.

The inner arm of the bell-crank 6 has pivotally coupled thereto one endof an oper ating bar or rod 12, the rear portion of the par operatingfreely through a lug or bearing 13 clamped or otherwise secured to thehandle 4, said bearing being of course adjustable along the handle. Onceadjusted, the bearing 13 forms a ixed abutment for one end of acompression Aspring 14 coiled about the bar 12, the rear end of the sprnbearing againsta guard 15 at the rear en of the actuating bar or rod 12.

The operation of the wiper is apparent from the foregoing description,and is substantially as follows: The handle 4 is held by the hands H,H', of the operator substantially as shown in Fig. 1. Should any dirt,leaves, grasses and the like adhere to the rake-teeth, or any stones orearth lodge between the teeth, the operator pushes the hand H', againstthe guard 15, thereby compressing the spring 14 and forcing the bar orrod 12 outwardly. This will oscillate the bell-crank 6 outwardly (seedotted position in Fig. 4) causing the straps 9, 9, (the arms 9 ofcourse are to be regarded as parts of the straps) to push the plate 11along the teeth, and thus wipe the teeth. The teeth are thus kept cleanand the spaces between them are always open and unobstructed. Uponrelease of the guard 15, the spring 14 expands, drawing the actuatingrod 12 rear ward, whereupon the bell-crank 6 oscillates in a reversedirection, the plate 11 is restored to its original position, and theteeth are again wiped. ThusV the teeth are wiped with each stroke of thereciprocating wiper plate or member 11. lt will be seen that with anoutward oscillation of the bellcrank 6, the straps 9, 9, (which jointlyconstitute a connecting yoke between the bellcrank and the wiper plate11) clear the teeth, the straps (or yoke formed thereby) oscillatingaway from the teeth. This allows the plate 11 to descend along the teethsubstantially the full length of the teeth, thereby yeffectively wipingthe latter. The guard 15 has a concaved portion partially spanning theperiphery of the handle 4, the said guard freely riding along the handlewith the reciprocatons of the actuating rod 12. The bearing 13 isadjustable along the handle so that the tension of the spring 14 may beaccordingly adjusted.

Having described my invention, what l claim is 1. ln combination with arake comprising a toothed body and a handle, a perforated wiper memberreciprocable along the teeth ofthe rake, a bell-crank pivoted to thebody,

a yoke hinged to one arm of the bell-crank and having its terminalspivotally coupled to the wiper member, a rod positioned con-v tiguous tothe handle and having oneend ivotally cou led to the opposite arm of thebell-crank, a earing on the handle traversed by the rear portion of therod, a rearterminal guard on the rod and a compression spring coiledabout the rod and interposed between the bearing and terminal guardaforesaid.

2. In a toothed rake provided with a handle, a wiper operating tocleanse the teeth, a spring-controlled rod for actuating the wiper,andan adjustable bearing on the handle traversed by said rod and formingan abutment forone end of the spring controlling the rod. .In testimonwhereof I affix my signature, in presence o two witnesses.
